In the lighting device 10, since the probe fixture 500 is detachably connected with the calibration probe universal fixing frame 400, and the calibration plate 600 is detachably connected with the calibration probe universal fixing frame 400 through the adjusting member 700, and since the probe fixture 500 and the calibration plate 600 are mutually aligned, the calibration plate 600 and the probe fixture 500 are ensured to be consistent, so that a user can calibrate a camera by using the calibration plate 600 first, then the calibration plate 600 is detached, the probe fixture 500 is mounted, and the calibration plate 600 and the probe fixture 500 are ensured to be mutually aligned, so that the probe fixture 500 and the calibration plate 600 can be positioned at the same position, namely, the accurate alignment of the probe fixture 500 to the terminal 920 of a product is realized, and the accuracy of the probe fixture 500 to the detection of the product is ensured. In addition, by adopting the lighting device 10, the accuracy of the probe jig 500 on product detection can be realized only by using the calibration plate 600 for one-time calibration alignment, and the lighting device is particularly suitable for detecting mass products and improves the detection efficiency.

The above-mentioned lighting device 10, the probe fixture 500 and the calibration plate 600 are all protruded on one side of the UVW platform 200, so as to ensure that the probe fixture 500 and the calibration plate 600 can better contact with the terminals 920 of the product, so as to ensure the accuracy of the lighting device 10 in detecting the product, and ensure that the calibration probe universal fixing frame 400 has better flexibility.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
